hi in my app, I've got many points. If I want to speedup rendering, the fastest way seems combining them together into one VBO (one vertex array for multiple points) and then draw them with one call. What is optimal size of that array, does have OpenGL problems with allocating too big arrays on GPU ?? I also really need to store those points in CPU.

You usually can assume that you can use an arbitrary large vertex buffer and it should be just fine. However, you should tell us how many points do you plan to have. Thousands? Millions? More?
